Insights
A risk-based oral health program effectively reduced caries in white-collar families by targeting children with mutans streptococci (MS). Different strategies are needed for blue-collar families to prevent childhood tooth decay.
Area of Science:
- Pediatric Dentistry
- Public Health
- Preventive Medicine
Background:
- Traditional oral health programs (OHPs) require new approaches.
- Evaluating a risk-based OHP against a standard program is crucial.
Purpose of the Study:
- To assess the preventive efficacy of a risk-based OHP compared to a traditional OHP.
- To identify factors influencing caries development in young children.
Main Methods:
- A cohort of 794 Finnish children (18 months to 5 years) was studied.
- Mutans streptococci (MS) screening identified children for targeted intervention.
- Intervention included health education and xylitol for MS-positive children.
Main Results:
- The risk-based OHP significantly reduced caries in white-collar families (NNT=3).
- Early MS colonization, caretaker occupation, and gender were linked to caries risk.
- The program showed effectiveness in white-collar families.
Conclusions:
- Targeted, risk-based OHPs can decrease caries in white-collar families.
- Alternative prevention methods are necessary for blue-collar families.
- Early identification of MS colonization is key for effective OHP targeting.
Background:
New perspectives are needed for oral health programmes (OHPs). The aim was to evaluate the preventive effect of a risk-based OHP in comparison with a traditional programme.
Design:
An age cohort of 794 Finnish children, 446 in the intervention group and 348 in the control group, was followed from 18 months to 5 years of age. The children were screened for mutans streptococci (MS) in the dental biofilm. The main outcome measure was the proportion of children with dental caries (decayed, missing, or filled primary teeth > 0) at the age of 5 years. The intervention, targeted to MS-positive subjects in the intervention group only, was based on repeated health education to the caretakers and xylitol lozenges for the child. Dental hygienists carried out the programme.
Results:
OHP was effective in white-collar families [numbers needed to treat (NNT) = 3, 95% CI 2-11]. Factors significantly associated with caries at 5 years were MS colonization at 18 months, occupation of caretaker, but also gender when incipient carious lesions were included in the index.
Conclusion:
Early risk-based OHP, targeted to the families of MS-positive children, can reduce the risk for caries in white-collar families. For blue-collar families, different kinds of methods in caries prevention and support are needed.

Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
